Application filed October 21, 1907. Serial No. 398,491.

To all whom it may concern:

Be it known that we, J OHN GEORGE AULsn- BROOK KITCHEN and ISAAC HENRY STOREY, subjects of the King of Great Britain and Ireland, and residents, respectively, of Lancaster, in the county of Lancaster, and of Ambleside, in the county of l/Vestmoreland, England, in the Kingdom of Great Britain,

provements in Pneumatic Tires, of which the following is a specification.

This invention relates to improvements in the construction or arrangement of thecover or jacket parts of pneumatic tires composed of segments having interfitting ends and the invention has for its objects to enable the tire to be quickly put together and repaired when damaged, and to obtain a tight joint at the seams of the cover.

The improvement consists of making the tire cover ofsegments open at their base portions and their ends, each alternate segment having two wedge like ends or pro jcctions fitting into the overlapping ends of the two adjacent segments, and a ridge of softpubber projecting" from the periphery of said alternate segments and extending be tween and engaging the ends of the adjacent segments.

On the drawings attached hereto l igure 1 shows an elevation of a portion of a tire made in accordance with this invention and fitted to a rim of the well known clencher tire; Fig. 2 shows a longitudinal section of the same and Fig. 3 a cross section on line The cover consists of a number of altereach. The segments 1 are built up as'usual of india rubber and canvas, the canvas'not bein indicated separately on the drawing, and Trave the usual configuration of a tire in section, being .split with the opposite edges 3 and 4. provided with heading 6 and 7 to enter the ateral recesses of the rim 8. They areopenjat both ends and may be conical at the ends as shown. The alternate segments 2 have wedge shaped ends 5 fitting within the ends of segments 1 and extending throughout the internal transverse len th of the same. They are preferably made thin, so that they can be easily folded toa smaller diameter than the segments 1 to facilitate their bei'n pushed into the ends of the segments 1. The segments 2 are each formed with a ridge 9 of soft india rubber,

which may project above the adjacent ridge comes on the ground in driving, be-

comes flattened and thereby pressed against the edges of the two adjacent segments 1 and makes a water and dirt tight joint against them. When the ridges project as shown, thesegments 1 are preferably formed with corresponding ridges 10 which prevent slipping. I

The segments 1 are clamped to the rim in the usual way by'bolts ll'disposed near to their ends. One of these segments is first. fixed on, then a segment 2 pushed into it and the next segment 1 is placed over its projectingend and so on. Each of the segments 1 can readily be taken ofl', repaired and replaced without disturbing the others.

The air tube is not shown in the drawings, but is in all cases a continuous tube.

1. A pneumatic tire comprising a plurality of segments open at their ends and at wedge-like arts interfitting in overlapping relation to form a continuously closed cover, and. a transversely disposed ridge of soft rubber extendlng between and engaging the ends of adjacentsegments and serving upon the imposition of pressure to spread or hat ten against said segments.

2. In combination, a wheel rim, a plurality of segments open at their ends and at their base portions adjacent said. rim, the open ends of aid segments having interfitting overlappin parts extending throughout the length 0% one se ent being adapted to fit internally and t e parts of the segment adjacent thereto being adapted to fit externally upon said first mentioned segment, said segments having said internal parts provided. with a peripherally disposed ridge of soft rubber adapted to flatten against the exterior overlappin parts of the adjacent section and upon t e imposition of pressure, and means for securingsaid segments to said rim.

In testimony whereof we have hereunto ailixed our signatures in the presence of two witnesses.
